Java Question

Populate dynamic values into JBPM select box

I had tried implementing org.jbpm.formModeler.core.config.SelectValuesProvider and compiled my code and created a jar , also include a blank bean.xml in "/src/main/resources/META-INF"

Added the jar in JBPM classpath but i couldn't able to see anything listed in the jbpm data provider combo box.

My code is given below :

import org.jbpm.formModeler.api.client.FormRenderContext;
import org.jbpm.formModeler.api.model.Field;
import org.jbpm.formModeler.api.model.RangeProvider;
import org.jbpm.formModeler.core.config.SelectValuesProvider;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.HashMap;
import java.util.Locale;
import java.util.Map;

public class ProductRangeProvider implements SelectValuesProvider {

@Override
public String getIdentifier() {

String identiferName = "deparmnet";
return identiferName;
}

@Override
public Map<String, String> getSelectOptions(Field field, String currentValue,
FormRenderContext formDetails, Locale locale) {
Map<String, String> maps = new HashMap<String, String>();
String employee = "";
String department = "";
String DbIp = "jdbc:mysql://*********:*****/****";
String userName = "***";
String password = "****";
Connection con=null;
try{
Class.forName("com.mysql.jdbc.Driver");
con=DriverManager.getConnection(DbIp,userName,password);
PreparedStatement stmt=con.prepareStatement("Select role from role_master");
ResultSet rs=stmt.executeQuery();

while(rs.next()){
maps.put(rs.getString(1), rs.getString(1));
}
con.close();
}
catch(Exception E){
System.out.println(E);
}
finally {
try {
con.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return maps;

}
}


Is there any configuration required for JBPM to identify my class just like workitemHandler definition .?

Answer

Try adding jar file in class path. This will resolve the issue .
